Magnetar (magnetic star) is found:
A powerful type of neuron star that puts off a powerful magnetic field, called a Magnetar has been discovered. This type of star is formed as a result of a a gravitational collapse of a star (progenitor star) as it dies and forms a supernova.
Current theories upset:
Scientists estimate that the original star that went super nova had to have been at least 40 times greater than our sun. Now, normally a collapsing star of this size would create a black hole. This one did not, instead it formed a magnetic star or Magnetar/neuron star. This turns established theories on their heads.
google reports “The mainstream assumption is that stars of between 10 and 25 solar masses go on to form neutron stars. But those above 25 solar masses produce black holes — the light-gobbling gravitational monsters that are formed when a massive, dying star collapses in on itself.”
Where is it?
As reported on the BBC news, “The new magnetar was found in an extraordinary star cluster known as Westerlund 1, located 16,000 light years away in the southern constellation of Ara (the Altar). This region contains numerous massive stars.” “Dr Ritchie remarked that if the Earth was “located at the heart of this remarkable cluster, our night sky would be full of hundreds of stars as bright as the full Moon”.”
Westerlund 1 was discovered in 1961 by a Swedish astronomer and is a favoured observation site in stellar physics.
What scientists really know about this:
Scientists believe that massive stars collapse earlier than small stars because the pressure on the core is greater causing them to burn up their hydrogen faster than smaller stars. “The astronomers assumed that this star formed at the same time as others in the same cluster. So the fact that this star had already collapsed shows that it must have been more massive than the other stars that still exist there.”
Already making new asumptions?
Stars usually form black holes when they are 25 percent larger than our sun. These scientists begin to assume again. “Dr Negueruela of the University of Alicante in Spain, a co-author on the study, said that the mystery of the missing black hole might be explained if the progenitor star got rid “of nine tenths of its mass before exploding as a supernova”.
One way of achieving this “diet plan” would be if the progenitor was part of cosmic double-act known as a “binary star”, and its companion pulled off some of its mass, Dr Clark, another co-author, told the BBC. This would have allowed it to avoid the fate of becoming a black hole.”
“Professor Mike Cruise, an astrophysicist at the UK’s University of Birmingham, who was not involved in the study, told BBC News that the new research was “a brilliant piece of detective work”.”
This is all truly interesting, but these scientists are relying on allot of assumptions. Millions upon millions of dollars are spent each year promoting any one of these assumptions only for them to find out, they were wrong. Then, there they go again, making up a new story“out of thin air” to explain what just happened. I notice, their ideas of the whole thing, have to fit within what they already presumed. Do they ever say, oh maybe we were wrong?
